安西榆林窟的岩土工程问题及防治对策

Problems and Control of Geotechnical Engineering of Anxi Yulin Grottoes

本文阐述了安西榆林窟的岩土工程问题 ,即岩体开裂、崖面风化、冲沟发育、大气降水入渗等。同时 ,也阐述了解决上述岩土工程问题的防治对策。其中锚索技术、利用PS -F材料进行砂砾岩石窟裂隙灌浆技术、崖面防风化化学加固是首次在石窟文物保护中的大规模应用 ,并取得了显著的效果。本文还就榆林窟今后的保护工作提出了建议。

This paper expounds the geotechnical engineering problems which includ es rock mass cracking, rock surface weathering, gully erosion, precipitation in fluent seepage and so on at Yuling grottoes, and also expound the measures of th e prevention and control of these problems. The measures that include anchoring, grouting of PS-F material and anti-weathering reinforce of cliff surface are th e first large scale application and achieve complete success. Finally, this pape r also makes a suggestion of the conservation of yulin in the future.
